The information provided in the attached report is in ,
response to that request.
Wisconsin Electric' agrees that erosion-corrosion of piping systems is a serious matter. Because of this, we have undertaken a substantial inspection program to accurately assess the current existing conditions of our piping systems.
Repairs or replacements of piping components will be accomplished as inspection results and engineering evaluations dictate.
If you have any further questions, do not hesitate to contact us.
Very trul yours

Selecting Points At Which To Make Wall Thickness Measurements j (1) Philosophy of Exam Point Selection Areas to be inspected for the 1987 Unit I refueling outage were selected based on the consequences of a component failure and the likelihood that service.related degradation was occurring. Using this
)
two-fold criteria, a sample of approximately 4% of all possible examination points was looked at. Expansion of the inspection program beyond the original sample size was anticipated had exam q results warrented it. A similar program is planned for the upcoming 1987 Unit 2 refueling / maintenance outage. j l
Systems whose failure could result in significant personnel injury or l equipment damage are considered for inspection. Those syst(ms whose j contained fluid temperature is less than 140 F, or whose pipe !
diameter is less than, or equal to, 1 inches, are excluded from j inspection without further evaluation. Failure of this category of piping would not have any substantial consequences. Piping systems which do not meet these criteria are evaluated separately for potential inspections.

ATTACHMENT NES4.CWK.IEB.87-01. RESPONSE Page 2 Points of inspection are selected using a relative " badness factor" and past industry experience. A " badness factor" provides a-
' relative measure of a components susceptibility to service related degradation.
Eacn system to be evaluated is subdivided inte sections based on geometry, pressure, temperature, and flow conditions. Figure A-1 .
.provides a sample of how a typical system is sWodivided. .Each subdivided section is then. evaluated and a relative badness factor for erosion-corrosion is calculated. The badness factor is calculated by a computer program according to the methodology shown in Response 3.
By comparing the relative magnitudes of the erosion-corrosion, !
badness factors for a given system or piping section, a qualitative l decision can be made as to where the most likely location is for i service related degradation. As the magnitude of a component's badness factor increases, so does its likelihood to experience degradation.
Thereby a method exists for screening potential points for inspection.
Table B-3 is a listing of the exam points selected for the 1987 Unit 1 outage and their associated badness factors.
As an example, suppose the erosion-corrosion badness factors for five points are as follows:
Point E-C Badness Factor A 5 g B 150 l C 20 i D 10 E 1 Point B would be chosen as the most likely candidate for erosion-corrosion to take place whereas Point E would be the least likely. 1 In selecting a sample of exam points for inspection, the piping !
sections most susceptible to degradation, those points with the ;
highest badness factors, would be selected for inspection. !
To qualify the method of selection, an additional random sample equivalent to 56 of the overall sample is taken. In other words, if 1 the original sample size was 100 points, 5 additional points picked l~ randomly, with no regard to their badness factor, are added to the inspection program. In this way a qualitative check of the selection process exists. If service related degradation is noted in this random sample, the selection process would become suspect and further evaluation of the process would be required.

Main steam Extraction steam Radwaste steam-Turbine exhaust & crossunder steam Feedwater heater and MSR drains & vents Hain feed Condensate Heating steata (3) Points of Inspection There were 3000 areas in Unit 1 evaluated for inspection. Of these 3000 areas, 115 were selected for inspection including a 10% random sample of the original sample for selection qualification purposes.
This amounts to a 4% sample of all the possible points of inspection.
- b. Basis For The Frequency of Wall Thickness Measurements The frequency of inspection is based on the proximity of the actual I minimum measured wall thickness to the minimum required wall thickness, as calculated in USAS B31.1, 1967 edition. Proximity to the minimum required wall thickness is determined by establishing a useful remaining life for a given piping component. The predicted useful remaining life (L) is defined as; L= EeSs-tmfg LWR l where, tmjg3= Minimum measured wall thickness in inches for a given piping component, tmjn

= Required minimum wall thickness in inches as calculated in accordance with USAS B31.1-1967. !
LWR = Maximum annual local wear rate in inches / year I
L_-____
' ATTACHMENT IEB 87-01 RESPONSE
, Page 4 i
The maximum annual wear rate is based on actual changes in wall thickness over a specific period of time. However, for those cases where no previous data exists for a given piping component, wear rate is based on the difference between nominal pipe wall thickness and minimum pipe wall thickness over an assumed 5 year period of time.
Maximum annual local wear rate (LWR) is calculated as follows;
"~
LWR = $hSs (1)
T LWR = tm n,- tg gr 2)
T where, tnom = Greater of either the standard ASTM nominal wall thickness or the average wall thickness derived from the highest 2 to 3 wall thickness measurements taken during the exam.
T= Time between measurements in years.
If no previous wall thickness measurements exist, assume 5 years.
tggn,= Hinimum measured wall thickness for a given piping component y
at time 1 tmin
= Minimum measured wall thickness taken at the same 2 1 cation as.tg n, but at time 2.
Equation (1) is used when data does not exist from a previous inspection while equation (2) is used when data does exist from a previous inspection.
The frequency of inspection, based on predicted useful remaining life (L), can be established as follows:
Life Remaining (L) Inspection Interval (yrs) (yrs) 1 to 3 1 l 4 to 12 L-2 l
Any area with a useful remaining life of greater than 12 years will be inspected at a frequency dependent on inspection result of similar areas. No specific program guidelines have been established for areas with a predicted useful life greater than l'2 years.
o 4
ATTACHMENT IEB 87-01 RESPONSE Page 5 It should be pointed out that this type of inspection program is based on .a percentage of the total possible number of exam areas. As more experience is gained in the area of erosion-corrosion within the industry and at FBHP, the sample size and the sample members may be altered.
Since no previous data existed for wall thickness measurements prior to 1987, the wall loss rates and the predicted useful remaining life values used in this report are extremely conservative. The wall loss rates presented for all exam areas were calculated in accordance with equation (1) above. It was assumed th:t all of erosion-corrosion took place over the last 5 years instead of the total 17 year operating history i' PBNP Unit 1. Also, it was assumed that at the beginning of its service life the components wall thickness was the greater of either tne standard ASTM nominal wall thickness or the average of the highest 2 to 3 wall thickness measurements taken. By allowable fabrication tolerances, as specified in the ASTM standards, it is quite possible that the pipe or fittings originally installed had a wall thickness that was as low as 12.5% below the specified nominal wall thickness. Taking these factors into account, the actual predicted useful remaining life could be as much as 5 times greater than that listed in this report.
Although a predicted life of 0 or 1 year may be assigned to a given area, it is highly likely that the actual remaining life of the component will be considerably more than that reported. However the values for wear rate and predicted useful remaining life provide a good relative comparison for determination of inspection intervals.
- c. Examination Techniques For Measuring Wall Thickness Wall thickness measurement are taken using A-scan UT techniques. Each area to be examined for wall thickness is sectioned by procedure into small grid spaces and each grid space is scanned 100% with UT. The minimum wall thickness for each area is noted for each area on a data sheet. Figures A-2 and A-3 depict a typical grid system used for wall thickness measurements.
The A-scan UT technique was chosen to overcome the shortcomings of digital readout UT devices. Digital readout UT devices which do not provide a presentation of the reflected sound energy, may misrepresent small sites of thinned areas or the edge of a larger thinned area. !

- d. Basis For Replacement / Repair Decisions ,
Pipe wall thinning, as indicated by NDE, is rejectable according to the following . criteria, unless a detailed evaluation can justify continued operation.
(1) -Reject'and repair the pipe if wall thickness is less than the
' minimum allowed by USAS B31.1 - 1967.
(2). Reject and repair the pipe if wall thickness, minus annual wear, is less than the minimum allowed by USAS B31.1 - 1967.
If signs of erosion-corrosion are present, but the remaining useful life of the piping component is greater than 1 year, the piping component may be placed back in service for I additional year. Following this period of service the piping component will be reinspected and evaluated as before.
Other areas exhibiting erosion-corrosion, but with a useful remaining life of greater than 2 years, will be reinspected as described in Response 2(b).
Those areas that have a predicted useful remaining life of less than 2 years will be seriously considered for replacement and/or repair as the need warrants. !
Request 3 For liquid-phase systems, state specifically whether the following factors have been considered in establishing your criteria for selecting points at which to monitor piping thickness (Item 2a):
- a. Piping material (e.g., chromium content)
- b. Piping configuration (e.g., fittings less than 10 pipe diameters apart)
- c. pH of water in the system (e.g. , pH less than 10)
- d. System temperature (e.g., between 190 and 500 F)
- e. Fluid bulk velocity (e.g. greater - than 10 ft/s)
Response 3 Erosion-Corrosion Badness Factor A qualitative ranking of a given area's susceptibility to erosion-corrosion, relative to other areas within a given piping system, can be made through the use of a badness factor. The badness factor takes into account fluid ,
temperature, steam quality, geometry, and flow velocity. The erosion-corrosion badness factor used for the PBNP inspection program was based on the Keller Equation described in EPRI report NP-3944, " Erosion-Corrosion in Nuclear Steam Piping: Causes and Inspection Program Guidelines."

.The erosion-corrosion badness factor, mee, can be calculated as follows:
mee = (mft)x(msx)x(mke)x(me) mft = temperature factor from Figure A-4
.msx = steam quality factor x =. Steam quality for two-phase flow use (1-x)*5 for subcooled flow use 1 L mke = geometry factor.from Figure A-5 if flow is disturbed (the upstream flow is not through straight pipe for at least 10 pipe diameters) multiply mke by; 0.5 if low disturbance 1.0 if medium disturbance i 2.5 if high disturbance me = Velocity in ft/sec The use of a factor for oxygen concentration and pH was not included. It was assumed, for all cases, that the relative contribution of these factors to the badness factor is the same for all exam points. In other words, variations in pH or oxygen concentrations are not used to further limit the selection sample size.
The badness factor relationship, described previously, is applicable only for carbon and low alloy steels. ;The badness factor is set equal to 0 for austenitic stainless steel due to its proven immunity to erosion-corrosion.
Request 4 Chronologically list and summarize the results of all inspections that have been performed, which were specifically conducted for the purpose of identifying pipe wall thinning, whether or not pipe wall thinning was discovered, and any other inspections where pipe wall thinning was discovered even though that was not the purpose of that inspection.

' Response 4 l The response to the above request will be in two parts. The first part vill be a summary of the pre-1987 inspection and repair program associated with erosion related piping damage. The second part will be a detailed account of the newly installed erosion-corrosion monitoring program. ;
- a. Pre-1987 erosion inspection and repair program.
At PBNP, considerations regarding the erosion of carbon steel steam piping have been addressed for nearly 15 years. Through careful and responsible l maintenance efforts, no eroded pipe or component has resulted in a l catastrophic failure. Minor through- wall leaks have occurred during the 1 17 and 15 year operating histories of PBNP Units 1 and 2 respectively. The j first recorded case was in 1973, 3 years after Unit 1 went into operation. l A through-wall leak wat observed in a 12" extraction line with a nominal l wall thickness of 0.437 inches. In only 3 years time, the wet steam had eroded through the carbon steel pipe wall at a rate of 0.147 in/yr. As a 1 result of prompt maintenance action, however, major pipe failures have been avoided.
As a result of several extraction line failures in the utility industry, PBNP undertook an extensive inspection program to assess the condition of the Unit 1 and 2 extraction lines. The program was conducted during the Fall of 1982 and the Spring of 1983, for Unit 2 and Unit i respectively.
Wall thickness measurements were taken on all areas within the extraction lines that were considered potentially susceptible to two-phase erosion-corrosion.
The results of the inspection indicated that extensive two-phase erosion-corrosion was occurring at the elbows and tees in the extraction lines, The extraction lines were fabricated from components with the following characteristics:
Nominal ASTM Pipe Component Nominal ASTM Size (in) Type Wall (in) Spec 12 Pipe 0.438 A106GRB Fittings 0.438 A234GRB 18 Pipe 0.438 A106GRB Fittings 0.438 A234GRB

'Some elbovs inspected had local measured wall thicknesses as low as 0.060 finches. This amounted to a wall loss rate of 0.031 in/ year if a 12 year operating history is assumed.
' Prior to' returning the units to service, all areas that were thinned significantly were reinforced with welded pipe patches. In 1984.all of the extraction lines for' Unit -1 and' 2 were replaced with ASTM A312 TP304 stainless steel piping and fittings. Since stainless steel of this type is immune to'erocion corrosion, the problem of wall. thinning in the extraction
-lines was eliminated.
l
.Two-phase. erosion-corrosion of the carbon steel (A53 GRB) turbine crossunder lines has been noted since the early days of. plant operation.
Local wall thinning has been significant enough to penetrate the 0.500 nominal wall carbon steel crossunder line. The first reported case of this
~ was in 1979 on Unit 1, when a through wall leak occurred on an elbow.
Annual visual inspections of the crossunder piping supplemented with UT wall thickness measuremen#.., are conducted from the inside surface to identify areas requiring sepair. Repairs are made during the annual refueling / maintenance outage as the inspection results dictate.
To reduce the erosion-corrosion rate of the turbine crossunder piping, moisture removal equipment has been installed in Unit 1 (Spring 1987) and will soon be installed in Unit 2 (Fall.1987). This equipment removes a large percentage of the entrained water from the high pressure turbine exhaust before it. enters the crossunder piping. The steam quality in the crossunder piping is therefore improved and the risk of erosion-corrosion damage to the piping is reduced substantially.
- b. Current erosion-corrosion inspection and repair. program (1) Program description The current erosion-corrosion' inspection / maintenance program was initiated during the 1987 Spring Unit 1 refueling / maintenance outage.
The purpose of the inspection program is to detect and quantify significant service related degradation in.the piping systems and pre-existing conditions that could jeopardize the integrity of these systems in the future. Representative areas of systems are inspected with various NDE techniques to detect such degradation and conditions.
The underlying objective of the inspection program is to look at piping system whose failure could result in significant hazards to personnel or equipment daiaage, of those systems, areas most susceptible to service related failures are targeted for inspection.
The primary concern is to locate areas of severe erosion corrosion in carbon steel piping prior to tL' occurrence of a leak or catastrophic rupture.

Main Feed Condensate 115 inspections were conducted using A-scan UT techniques as previously l
- described in Response 2c. In addition, direct visual examinations of large diameter pipes (i.e. crossunder' pipes) were performed from the inside surface to supplement the UT exams.
Each exam area was uniquely identified with a number such as MS-24-EB-01-1102. To permit accurate location of the exam areas, isometric drawings, showing each individual exam area within a piping system, were developed.
To permit repeatability of successive wall thickness measurements on sections of a piping component, a gridding methodology was developed. By procedure, a grid system was drawn on the outside surface of the piping component. The area within each grid section was scanned 100% with UT instrumentation and the minimum observed wall thickness was recorded.
This was done for each grid section. This method will provide repeatability from year to year and will provide complete coverage of the piping components entire pressure retaining wall.
(2) Results Of Inspections 1987 Unit 1 (a) Thickness Measurement Summary Several areas were discovered to have observable wall thinning.
Most notable were the turbine crossunder lines which had extensive areas of tiger striping (Figure A-6) and erosion damage. Some areas had wall thinning of up to 50% of the original nominal wall. As noted in 4a above, turbine crossunder >
' lines have been observed to have had significant erosion-corrosion problems for many years and have necessitated annual inspections and repairs at Point Beach. Thus, the w 2; losses observed during the U1R14 inspections were expected.

ATTACHMENT IEB 87-01 RESPONSE Page 11 Of the 23 areas inspected in the crossunder lines, nearly all of them had some indication of-thinning. Three areas had worn to the point where repairs became necessary. Figures A-6 through A-8 are examples of the type of erosion noted in the crossunder lines.
Wall thinning was also noted in some of.the main steam, main feed, and feedwater heater drain lines. Eleven areas inspected showed varying degrees of evidence of wall thinning, but none were significant enough te require immediate attention. The areas that showed evidence of wall thinning were at locations where geometries changed such as at tees and branch connections.

The predicted useful remaining life, based on a conservative wall loss rate of 0.013 in/yr, is 3 years. Based on the degree of wall loss and the uncertainty of the wall loss rate, this fitting will be reinspected in 1988.
xv MS-30-EB-01-1306, 30" tee Location: Main steam line upstream of non return valve ASTM nominal wall thickness: 0.908 in.
Measured nominal wall thickness: 1.570 in.
Measured minimum wall thickness: 0.960 in.
Description:
Wall thinning, as indicated by UT, was noted on the branch portion of the tee. .The maximum wall loss was 38% of the measured nominal wall thickness. By a conservative estimate of the wall loss rate, the predicted wall thickness will reach the minimum required wall thickness in one year. It should be noted that the wall thickness variations noted are within the original fabrication tolerances of ASTM A155. ,
It is therefore possible that this condition has existed since the piping was originally installed and no wall thinning has actually occurred. This area will be reinspected in 1988 to confirm this.

Location: Inlet to SB feedwater heater ASTM nominal wall thickness: 1.28 in.
Measured nominal wall thickness: 2.10 in. j Heasured minimum wall thickness: 1.18 in. '
Description:
Wall thinning, as indicated by UT, was noted on the run of the tee. The maximum wall loss was 44% of the measured nominal wall thickness. By a conservative estimate of the wall loss rate, the predicted wall thickness will reach the minimum required wall thickness in one year. It should be noted that the variations in wall thickness noted are within the original fabrication tolerances specified under ASTM .
A106 GRB. It is therefore possible that this condition has existed since the piping was originally installed and no wall thinning has actually occurred. This area will be reinspected in 1088 to confirm this.
Request 5 Describe any plans either for revising the present or for developing new or additional programs for monitoring pipe wall thickness.
Response 5 The current inspection program was implemented for the first time during the 1987 Unit 1 refueling outage. It will also be used for the upcoming 1987 Unit 2 refueling outage. As the current program is based on EPRI report 3944 and existing WE and industry experience, it is likely changes will be made to the program as new information becomes available.
Once the most susceptible areas for erosion-corrosion have been clearly identified, and reasonable erosion-corrosion wall loss rates established, the ;
s.,ple size and its constituents may be revised. Our inspection policy has been conservative to ensure that PBNP Units 1 and 2 are operated in a manner that will ensure the safety of the public, operating personnel, and plant ,
equipment. l l
